Abstract:A PTP approach in network security for misbehavior detection system present a method for detecting malicious
misbehavior activity within networks. Along with the detection, it also blocks the malicious system within the network and adds
it to Blacklist. Malicious node defined as a compromised machine within the network that performs the task provided by i.e. it
does not forward the legitimate message to another node in the network or sends some other message to a neighbor node. This
system is based on Probabilistic threat propagation. This scheme is used in graph analysis for community detection. The
proposed system enhances the prior community detection work by propagating threat probabilities across graph nodes. To
demonstrate Probabilistic Threat Propagation (PTP) considers the task of detecting malicious node in the network. Proposed
System also shows the relationship between PTP and loopy belief propagation.
